How about Emacs 26? We usually consider it OK to drop support for things that are "older than Debian stable" or thereabout. But usually it depends a lot on the cost of maintaining this backward compatibility. In this case, the cost seems to be very reasonable, so I see no reason to drop support for GnuTLS2 at this stage. Those tradeoffs change over time, so by Emacs-26 it's quite likely that we'll get rid of GnuTLS2 support, indeed. Stefan
